JOHN H. WOOD, OF CHARLESTON, ILLINOIS.

DAM PER-REGU LATOR FOR STOVES.

SPECIFICATION forming part of Letters Patent No. 486,314, dated November15, 1892.

Application filed February 23, 1892.

To all whom it may concern:

Be it known that I, JOHN H. WOOD, a citizen of the United States,residing at Charleston, in the county of Ooles and State of lllinois,have invented anew and useful Damper- Regulator for Stoves, of which thefollowing is a specification, reference being had to the drawings, andto the letters of reference marked thereon.

' Figure 1 is a side elevation of a stove or range to which I haveapplied my improvements. Fig. 2 is a vertical longitudinal section ofthe same. Fig. 3 is a transverse vertical section showing thereservoir-damper open. Fig. t is a similar view showing the damper shut.Fig. 5 is adetail view hereinafter referred to.

My present invention relates to stovedampers.

The improvements consist in applying to a stove, preferably acooking-stove, a mechism or device so disposed and arranged thatWhenever the oven-door is opened the dam per which controls the finesfrom the stove to the Water-back or reservoir will be closed by the actof opening said oven-door and that when the oven-door is shut afterbeing opened said damper will remain closed, but at the same time freeto be operated by the usual handle. It will be understood that whenbaking the damper leading to the water-back must be closed. Otherwisethe heat will not be directed to the space under the oven and the latterwill not bake on the bottom. It will also be seen that in order to placeany article in the oven for baking the oven-door must necessarily beopened, and this act of opening closes this damper before the bakingaction takes place.

Referring to the drawings, A represents a stove or range provided with awater-back 0r reservoirB and aflue or fines 0, leading from the stove tothe water-back.

D is the damper or dampers, leading from the stove to the water-back andcontrolling the flue-passages 0, whereby the heatfrom the stove isdirected to the water-back or cut off therefrom and thrown down underthe flue or air-space beneath the oven. 4

E represents the oven-door, hung upon Serial No. 422,430. (No model.)

hinges F. This door carries a cam, eccentric, or projection G, rigidtherewith and moving with the door.

H is a sliding piece or bar adapted to have an endwise movement througha slot made in the side of the stove and suitably arranged in operativerelation with the cam G.

I is an elbow-lever pivoted at J to a lug or cars K, rigidly secured tothe stove or its lining adjacent to the oven-door E. The lower arm L ofthe elbow-lever I is pivotally conheated at M with the sliding bar H.The opposite end N of the lever I is projected inwardly and in thisinstance is given a double-rightangled bend, the extremity of which isfree to engage certain hereinafter-described parts. 6 5

D represents dampers covering the flue-passages, before referred to.

O is the rod upon which the dampers D are journaled, and P is the usualdamper-operating lever, attached to rod 0 outside the stove.

Q is a projection rigid with the dampersD and rod 0 and projecting outwithin the vibratory path of the end N of the elbow-lever I, so as to beacted thereon by said lever.

' The opening of the oven-door for the purpose of inserting any articleto be baked causes the cam or projection G, moving therewith, to engagethe outer end of the sliding bar H and force it inwardly. This inwardmovement of bar H causes the rocking of the elbow- 8o leverI upon itspivotJ by reason of its pivotal connection M therewith. An upwardmovement of the inner end N of said lever I ensues, and it comes incontact with the projection Q, secured to the dampers D, and closesthem, 8 should they be open, and, if not, the movements of the parts areidle.

When the dampers are closed by my improved dam per-regulator, theyremain so until opened by hand by the handle P.

Where the word stove is used throughout the specification it will beunderstood, also, that a range is meant or any other heat-ing device towhich my improvements can be ap plied. It should also be furtherunderstood 5 that in speaking of a water-back the usual reservoir of acooking stove or range is also included.

an operating-piece, a damper controlling the flue-passages to thewater-back, and mechanism arranged between the oven-door and the damperfor closing the latter upon open- :0 ing. the door, substantially asdescribed.

In testimony whereof I hereunto set my hand this 17th day of February,1892.
